Polymer dimethyl silicone doped with crown functionalized tetraphenylethene macrocycle: A high selection discriminating film for benzene derivatives

Recent advances in aggregation-induced emission (AIE)-based chemosensors for the detection of organic small molecules

“…227 Highly sensitive and selective detection of chlorobenzene vapour can be thus attained with an ultrafast response time of <1 s. Moreover, Liu and Zeng et al reported the doping of a novel TPE-crown ether macrocycle C5 onto PDMS film substrate, which is able to not only differentiate benzene from other VOCs (THF, 1,4-dioxane, pyrrole, and pyridine) via a blue-to-green-yellow emission change, but also discriminate iodobenzene from toluene, fluorobenzene, chlorobenzene and bromobenzene via a blue-to-dark-brown change. 229…”

Preparation and Applications of Polydimethylsiloxane‐Based Fluorescent Materials

“…[82] Zhang et al synthesized crown functionalized TPE macrocycle molecule and mixed it into PDMS to obtain a detection strip that can recognize benzene, which is shown as color transition from blue to yellow-green. [83] In previous studies, detecting pesticide residues by using conventional QDs through fluorescence quenching has emerged endlessly. [84,85] In this context, Yang et al used methylammonium lead halide perovskite quantum dots (MAPB-QDs) doped PDMS to prepare fluorescent colorimetric cards in order to detect the polar organochlorine pesticides (OCPs) in crops and the environment.…”

A fluorescent quaternary phosphonium main-chain-type polymer: an opportunity to fabricate functional materials with excellent antibacterial activity and bacterial imaging capability

“…Reasonably, this electrostatic attraction will further improve the emission capability from the typical AIEgen of TPE. 45,46 Moreover, the hydrogel formation ability 47 and film processability 48,49 of the most abundant natural and renewable organic polymer of cellulose are impressive to capture our research interests. Of course, the hydrogel formation ability of CNCs was concentration dependent, where when the concentration was less than 1 mg mL À1 , gels were hardly obtained.…”
